Guest Presiders

Below are brief profiles of several of the priests who regularly say Mass at the Sheil Catholic Center: 

Father Mark Andrews, SJ 

Fr. Mark Andrews comes from Chicago's Southwest Side. After graduation DePaul University, he worked in the business world for seven years, principally in the field of real estate appraisal. He entered the Society of Jesus in 1981 and was ordained a priest in 1992. He holds a Master's degree in Divinity from the Jesuit School of Theology at Berkeley in California, as well as a Master's degree in Catechetics from Boston College.  

As a Jesuit, Fr. Mark has taught Religious Studies at Loyola Academy in Wilmette and interned as a chaplain in the County Jails of San Francisco. For five years, he also served as Novice Director for his province, guiding new Jesuit recruits in their first two years of formation.

Since 2002, he has been assigned to Bellarmine Jesuit Retreat House in Barrington, offering preached retreats and individual spiritual direction.


Father Corey Brost 

Fr. Corey Brost is a priest with the Clerics of Saint Viator. With a background in journalism and law, Fr. Corey uses his experience to heighten public awareness of the needs of the marginalized and to directly advocate for them. He has served as a lawyer at Association House for young people living in poverty, and as a caseworker for REST Shelter for the homeless.  

Fr. Corey’s passion has been, and remains, working with teens in high school and parish ministry. He has authored a series of books for teens that connect the weekly Gospel messages to the ups and downs of their lives.  

Currently, Fr. Brost teaches religion at St. Viator High School in Arlington Heights.  


Father John Moulder 

Fr. John Moulder is a Chicago diocesan priest who joined the Sheil community as a guest priest in 2002. In his priesthood, he combines his love of ministry and love of music; in fact, he serves as Liaison to the Arts Community within the Archdiocese of Chicago. 

Fr. John's passion for the arts goes back to childhood in Illinois, where he started playing acoustic guitar at 10, began studying the instrument seriously at 12 and fell in love with jazz and blues at 14. Early in his life, he became interested in composing and has since written music in many genres, though primarily in jazz. 

His call to the priesthood came at age 24, and Fr. John was ordained in 1990. He continues to maintain music as a significant part of his life — in 2000, he received his Master of Music in Jazz Pedagogy from Northwestern University. He continues to play at jazz clubs and occasional concert venues.  

Father Jerry Overbeck, SJ 

For almost 30 years, Fr. Jerry Overbeck has lived and worked full-time at Loyola University of Chicago. He teaches liturgy as University Liturgist, and is chaplain of both the School of Law and the School of Social Work at the Water Tower Campus of Loyola.  

As he has done for most of his years at the University, Fr. Jerry lives with more than 400 first and second year undergraduates in a residence hall at Loyola, where he provides pastoral counseling.
